Title: Improvements in intercommunication coupling devices for use in cable connections between tugs, gliders and the like
IPC: B64D3/00
Filed: 1943-12-21
Abstract: 578,852. Communicating with aircraft. MALCOLM, Ltd., R., and LOBELLE, M. J. O. Dec. 21, 1943, No. 21403. [Class 40 (iv)] [Also in Group XXXVI] In a towing arrangement for gliders towed initially by two tugs a, b, one of which is disconnected when the glider c has become airborne, and in which telephonic communication is provided, the towing cable incorporates a releasable coupling k (see Group XXXVI) comprising switch means whereby a telephone circuit between the tugs is replaced by one between the principal tug a and the glider c. The towing cable connects the tugs and passes round a pulley on a junction member d which is connected to the glider by a forked bridle, a relaxation of the pull by the assistant tug causing the cable to be drawn through the junction member by the principal tug until a plug member h mounted on and insulated from the junction member, engages and releases the coupling, further movement being prevented by a spigot u on the cable. The telephone circuit is changed on disconnection by means of a switch incorporated in the spigot u (Fig. 6), comprising a thimble 18 sliding over a pin 33 which is connected to the central telephone wire 32. Normally, a spring plunger 17 maintains a sleeve 43, mounted on but insulated from the thimble 18, in contact with an annular conductor 38, thus connecting the cable g, which is used as a return conductor, through the sleeve 43 to a terminal on the coupling. On disconnection of the coupling, the plunger 17 releases the thimble 18 which is then urged outwardly and connects the cable 32 through the plug member h to a terminal mounted on and insulated from the junction member d, this terminal and a similar one connected to the junction member providing the connections for the glider telephone. Specification 572,780, [Group XXXIII], is referred to.

Title: Dispersions stabilised with polyelectrolytes
IPC: C08F2/24
Filed: 1976-05-24
Abstract: 1536445 Stabilized dispersions DOW CHEMICAL CO 24 May 1976 21451/76 Headings C3P and C3V Polyelectrolytes prepared by copolymerization of at least two monomers, at least one of which is hydrophobic and at least one of which can be converted to an ionic hydrophilic species of which at least some are subsequently converted to such a species, are used to stabilize dispersions. The polyelectrolyte is adsorbed at the disperse phase in a substantially flat configuration (i.e. the chains lie along the interface rather than perpendicular to it) and the area occupied by each hydrophilic unit at the disperse phase surface is 60-100 sq. Angstroms. The ionic units remain substantially completely ionized over the entire pH range of 0-14 and the polyelectrolyte has an adsorption coefficient equal to or greater than 1 at the point where the disperse phase is saturated therewith said constant being the amount of polyelectrolyte in the disperse phase divided by the amount thereof in the continuous phase. Exemplified polyelectrolytes are derived from dimethylaminoethyl methacrylate and butyl acrylate or styrene (subsequently quaternized) and methyl methacrylate and vinyl benzyl chloride (subsequently converted to vinyl benzyl sulphonium chloride groups). Polymer latices are stabilized therewith. The polyelectrolyte may be used as the stabilizer during the dispersion polymerization of unsaturated monomers, e.g. styrene and butadiene.

Patent GB-748154-A (GB)
Title: Improved process for the production of high quality lubricating oils
IPC: C10G71/00
Filed: 1953-08-06
Abstract: Lubricating oil is obtained by distilling a crude petroleum oil to yield at least two fractions boiling in the range 650-1200 DEG F., solvent extracting these fractions separately to remove aromatic constituents, and/or constituents containing sulphur, oxygen or nitrogen, freeing the raffinates of solvent, hydrofining each of the raffinates in the presence of a hydrofining catalyst under conditions whereby the consumption of hydrogen during the hydrofining operation does not exceed 200 cu. ft./barrel of raffinate feed, measured at 60 DEG C. and 30 ins. Hg., and then removing entrained hydrogen, hydrogen sulphide and ammonia from the hydrofined oil by passing in contact therewith a gas which is inert towards the hydrofined oil. If necessary, the raffinates from the solvent extractions may be dewaxed before being subjected to hydrofining.  Suitable solvents for use in the solvent extractions are phenols, furfural, liquid sulphur dioxide, nitrobenzene, aniline, cresols, chlorex, dimethyl formamide, dipropionitrile, liquid ammonia and amines.  These solvents may be used in conjunction with solventmodifying agents such as water, alcohols and esters.  The removal of wax from the raffinates may be accomplished by diluting the oil with a solvent such as liquid propane, chilling, filtering and then distilling solvent from the wax-free oil.  Suitable catalysts for use in the hydrofining operation are nickel or kieselguhr, molybdenum oxide or sulphide or alumina, cobalt molybdate or alumina, platinum or alumina, or a blend of nickel sulphide and tungsten sulphide.  The hydrogen may be supplied to the hydrofining operation as dilute hydrogen from a hydroformer or from the dehydrogenation of butylenes to butadiene. Preferred hydrofining conditions are a temperature of about 300-700 DEG F., a pressure of about 50-150 lbs./sq. in., a hydrogen recycle rate not exceeding 1000 cu. ft./barrel and a feed rate of about 0.5-10 v/v/hr.  The hydrofined raffinates may finally be brought to the original flash point of the oil and passed down a packed tower countercurrent to a flow of oxygenfree steam, nitrogen or other inert gas.  Apparatus for carrying out the process of the invention is described.  Specification 737,020 is referred to.

Abstract: 653.774. Machines for making ropes. SYNCRO MACHINE CO. Aug. 23, 1948, No. 22184. Convention date, Aug. 18, 1948. [Class 109] A safety switch for wire, hemp &c. stranding machines comprises in combination a pivoted arm 24 having a pulley thereon adapted to have a stranded cable 38 wrapped around it intermediate the drawing capstan 40 and the twisting die, an adjustable spring 33 bearing against the pivoted arm, and a switch 37 mounted adjacent the latter adapted to be operated by movement of the swinging arm resulting from a decrease in tension on the cable. As shown, the pivoted arm 24 comprises a channel member extending from a block pivotally mounted on a bearing 22 and provided at its upper end with two pulleys 26, 27. The spring 33 extends between a pair of washers 32, 34 on an adjustable screw 30, the washer 34 bearing against the forwardly extending portion of the angle from which the arm 24 is formed and the end of the screw extending through a slot in this angle part. The same part of the arm 24 also carries an adjustable screw 35 which, in the position shown, bears against the contact point 36 of the switch 37. In this position of the arm 24, the circuit to the driving motor of the strander, as well as the capstan 40, is broken and the stranding machine stopped. This results when the tension on the arm 24 due to the passage of the cable 38 over the pulley 26, 27 thereon becomes less than the pressure exerted by the spring 33 due to the breakage of a wire. In the normal position of running, the arm 24 occupies the dotted position shown. A single pulley may be used instead of the pair of pulleys 26, 27, but in the form. shown, these pulleys co-operate with a fixed pair of pulleys 18, 20, mounted on an upward extension 16 of the frame 10. The cable 38 passes around the pulleys 18, 20, 26 and 27 in the manner shown, the tension exerted on the arm 24 being multiplied accordingly.
